Sprint announced today it'll begin delivery of Samsung Galaxy S 4 (16GB) with the addition of Sprint Spark (enhanced LTE) to its sales channels in the next few weeks. This enhances the current version of Galaxy S 4 with a design change to take advantage of unprecedented speeds by combining all three Sprint bands (800MHz, 1.9GHz and 2.5GHz) of 4G LTE wireless spectrum.

Sprint Spark provides the capacity to greatly improve the performance of video and other bandwidth-intensive applications while opening the way for futuristic applications. Sprint Spark is designed to support a new generation of online gaming, virtual reality, advanced cloud services and other applications requiring very high bandwidth.

Sprint plans to deploy Sprint Spark in about 100 of America's largest cities during the next three years, with initial availability in five markets now. The first markets with limited availability are New York, Los Angeles, Chicago, Tampa and Miami. Sprint 4G LTE service is expected to be available by mid-2014 to approximately 250 million Americans, and Sprint expects 100 million Americans will have Sprint Spark or 2.5GHz coverage by the end of 2014.

This super-high-speed capability demonstrates 50-60 Megabits per second (Mbps) peak speeds today with increasing speed potential over time. Given Sprint's spectrum and technology assets, it is technically feasible to deliver more than 2Gbps per sector of over-the-air speed.

Samsung Galaxy S 4 with Sprint Spark will be available for $199.99 (excluding taxes) with a new line or eligible upgrade and two-year service agreement after a $50 mail-in rebate via reward card2 or $25 per month with Sprint One Up.
